Application Scenarios
In a municipal wastewater treatment plant, the existing ABB Advant OCS system needed to integrate new energy-efficient variable frequency drives (VFDs) from a third-party manufacturer that only supported Modbus RTU. The ABB PMA324BE PM-A324-BE HIEE400923R0001 was deployed as a cost-effective gateway. It mapped the drive parameters (speed, current, fault status) directly into the ABB controller’s process image. This eliminated the need for a separate PLC, reduced integration costs by 40%, and allowed the plant to leverage existing operator graphics without modification.
